Television broadcaster
Central operations distribute television content to stations and providers.
A television broadcaster or television network is a telecommunications network for the distribution of television content, where a central operation provides programming to many television stations, pay television providers or, in the United States, multichannel video programming distributors. Until the mid-1980s, broadcast programming on television in most countries of the world was dominated by a small number of terrestrial networks. Many early television networks such as the BBC, CBC, PBS, PTV, NBC or ABC in the US and in Australia evolved from earlier radio networks.

Lore & Background
Television networks originated from earlier radio networks, with early examples including the BBC, CBC, PBS, PTV, NBC, and ABC. In many countries, the terms 'television network,' 'television channel,' and 'television station' became interchangeable in everyday language, though professionals maintain distinctions. Networks may or may not produce all their own programming; production companies such as Warner Bros. Television, Universal Television, Sony Pictures Television, and TriStar Television distribute content to various networks, and some networks import programs from other countries or use archived programming. In North America, many cable and satellite television networks are branded as 'channels' because they are singular operations without affiliates, distributed via cable or direct-broadcast satellite providers. These are called 'specialty channels' in Canada or 'cable networks' in the U.S. Some stations have the capability to interrupt the network for local commercials, station identifications, and emergency alerts, while others break away for regional variation. The majority of commercial television stations are self-owned, though some are owned-and-operated by a network. Cable television enabled new channels targeting bicultural audiences, such as Latino audiences in the United States. Media historian Tim P. Vos noted that policymakers did not intend to create a broadcast order dominated by commercial networks, and legislative attempts were made to limit the network's preferred position. Modern network operations centers use broadcast automation and atomic time from GPS to maintain synchronization.
Reader's Guide
Television broadcasters and networks have been central to the distribution of television content globally, evolving from earlier radio networks. They operate by providing centrally originated programming to affiliated stations or directly to cable and satellite providers. The emergence of cable television expanded cultural programming, allowing networks to target specific audiences, such as bicultural Latino viewers in the U.S. The industry distinguishes between traditional networks with affiliates and singular cable channels. Networks may rely on production companies for content, import programs, or use archived material. Local stations can insert commercials or break away for regional programming. The adoption of digital television led to networks created for digital subchannels, focusing on classic series, films, music, or sports. Cable and satellite providers pay networks per subscriber, with ESPN commanding the highest rates. Some networks use brokered carriage deals, especially with low-power stations. The BBC, a major international broadcaster, is funded by a television license in the UK and by advertising through BBC Studios.

Frequently Asked Questions
What is a television broadcaster?
A television broadcaster is a telecommunications network that centrally curates or produces programming and then delivers it to numerous local stations, pay-TV operators, or multichannel video programming distributors. It acts as the hub through which most viewers ultimately receive their TV content.
How does a television broadcaster distribute its programming?
A central operation packages shows and feeds them out to affiliated stations, satellite or cable providers, and multichannel video programming distributors. This one-to-many model lets a single network reach audiences across an entire country or region without each station producing its own lineup.
Which networks are considered classic examples of television broadcasters?
Well-known broadcasters include the BBC, CBC, PBS, PTV, NBC, ABC, Fox, The CW, and MyNetworkTV. Many of these grew out of earlier radio networks before expanding into visual broadcasting.
How did television broadcasting evolve in the mid-20th century?
Until roughly the mid-1980s, a handful of terrestrial networks dominated TV programming in most countries. Over time the landscape diversified as cable, satellite, and digital subchannels gave rise to many more specialized channels.
What key technologies underpin modern television broadcasting?
Broadcast automation systems handle the scheduling and transmission of content, while GPS-based synchronization keeps multiple stations and providers in lockstep. Digital subchannels also allow a single broadcast signal to carry several distinct program streams simultaneously.
